Environment Variable that is a JSON object

Hi I have been trying to load a environment variable that is a JSON object (ie to load Google Cloud Service Account). In my env.mjs I added the following

const server = z.object({
 
  GCS_KEY: z.preprocess(
    (str) => JSON.parse(String(str)),
    z.object({
      type: z.string().min(1),
      project_id: z.string().min(1),
      private_key_id: z.string().min(1),
      private_key: z.string().min(1),
      client_email: z.string().min(1),
      client_id: z.string().min(1),
      auth_uri: z.string().min(1),
      token_uri: z.string().min(1),
      auth_provider_x509_cert_url: z.string().min(1),
      client_x509_cert_url: z.string().min(1),
    })
  )
 
})

const processEnv = {
  GCS_KEY: process.env.GCS_KEY
}

const server = z.object({
 
  GCS_KEY: z.preprocess(
    (str) => JSON.parse(String(str)),
    z.object({
      type: z.string().min(1),
      project_id: z.string().min(1),
      private_key_id: z.string().min(1),
      private_key: z.string().min(1),
      client_email: z.string().min(1),
      client_id: z.string().min(1),
      auth_uri: z.string().min(1),
      token_uri: z.string().min(1),
      auth_provider_x509_cert_url: z.string().min(1),
      client_x509_cert_url: z.string().min(1),
    })
  )
 
})

const processEnv = {
  GCS_KEY: process.env.GCS_KEY
}

but I am getting an error in the MergedOuput type, saying that some fields are missing. Any help would be greatly appreciated. Thanks

Is it possible to store a JSON file to an ENV variable with dotenv?

I am using Google Drive API with my Rails application. The API is working fine. I have the following client_secret.json file: { "type": "service_account", "project_id": "gobirdie-landing-page"...

yes - i am doing that - but the MJS file is complaining about a type issue - seen in the screenshot

stringify it and store it as a string, then json parse it during load
